Net Carbon Exchange in U.S. Crop Production
Based on U.S. crop production, scientists determined which American regions are carbon sinks, or those that take in more carbon than release it, and carbon sources, or those that release more carbon than they take in. Their calculations showed that the most agriculturally active regions, shown in blue, are carbon sinks while the regions with larger populations, shown in red, are carbon sources.
